A method for forming a seat belt through-bore in an automotive seat, which uses a lower die having an opening perforated therein and an upper die movable toward and away from the lower die, the method including the steps of providing a top cover member having an incision therein and two separate covering pieces sewn to a frontal surface of the top cover member such that they are disposed on the opposite sides of the incision, and turning upside down the thus-formed top cover member. In this method process, it is so arranged that, before lowering the upper die to press and bond the top cover member to a cushion member, the free portions of those two covering pieces are inserted into said opening of said lower die, so that the top cover member is placed flat upon the lower die, in order to avoid creation of undesired recession on the top cover member of resultant seat.
